Specification of Letters Patent.

Patented May 22, 1906.

Application filed August 3,1905. Serial No. 272,564.

To all whom it may concern.-

Be it known that I, ALEXANDER ANnEEws, a citizen of the United States,residing at Carbondale, in the county of Jackson and State of Illinois,have invented certain new and useful Improvements in Fluid-PressureRegulators; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to fluid-pressure regulators and one of the prjnc' pal objects of the same is to provide a device of comparativelysimple construction yvhich can be quickly adjusted to any requiredpressure desired within the scope of the pressure of the ma n.

Another object is to provide means whereby the pressure when onceadjusted may be automatically regulated by means of a weight.

These and other objects are atta'ned by means of the constructionillustrated in the accompanying drawings, 111Wl110h Figure 1 is a sideelevation of a fluid-pressure regulator made in accordance with myinvention. Fig. 2 is a central vertical section of the same. Fig. 3 is aperspective view of one of the cup-shaped leather valves. Fig. 4 is acentral vertical section of the perforated inner cylinder, and Fig. 5 isa perspective view of the holder for the small eupshaped leather valvesfor said inner cylinder.

Referring to the drawings for a more particular description of myinvention, the numeral 1 designates the outer casing or casting,provided with an inlet-opening 2 and an outlet-opening 3. Projectingfrom the casing are a pair of spaced bearing-lugs 4, to which a lever 5is pivoted at 6, said lever being connected to a piston 7 by a pin orscrew 8. Above the cylinder or casing 1 is a tubular cyl nder 9,threaded, as at 10, and connected to the casting 1, as shown in Fig. 2.The piston 7 has connected at its upper end a cupshaped flange 11, andsupported by said flange is a leather washer 12, which is of substantially cup shape, and fitted, within said washer is a disk 13, nuts14 and 15 serving to.

clamp the flange, the washer, and the cupshaped leather valve in place.This valve is adapted to slide with n the cylinder 9. At the lower endof the piston a valve-holder 16 is connected by a projecting threadedportion 17 to the piston, and at opposite ends this valve-holdersupports two oppositelydisposed cup shaped leather valves 18, saidvalves adapted to reciprocate within the inner cylinder 19, saidcylinder 19 being provided with series of perforations 20, as shown inFig. 4. A weight 21 is fitted to slide upon the lever 5 and is adaptedto be adjusted at such position upon said lever as to regulate the flowof water through the outlet at the degree of pressure desired.

From the foregoing it w. ll be obvious that my invention is ofcomparatively simple construction, is reliable and eflicient in use, andcan be quickly fitted and adjusted to the required degree of pressure.

Various changes in the form, proportion, and the minor deta'ls ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A fluid-pressure regulator comprising an' outer cylinder 9, a casing 1secured to said cylinder and provided with inlet and outlet openings, aninner perforated cylinder 19 secured Within the casing 1, a pistonprovided ,with a large cup-shaped valve 12 seated upon a cup-shapedflange 11 for operating in the main cylinder, aspool-shaped valve-holder16, a pair of oppositely-disposed cup-shaped valves 18, secured at theends of said holder by screws 17, and adapted to slide in the perforatedcyl'nder 19, a lever pivoted to the casing and connected to the piston,and a weight adjustable upon the lever, substanti ally as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

ALEXANDER ANDREWS.
